1、Surface modification of carbon fiber by vinyl functionalized silane to

In this paper, vinyl silane coupling agent was introduced on the surface of carbon fiber to participate the subsequent vulcanization of rubber for CFRR composites.

2、Silane Coupling Agents

Many conventional coupling agents are frequently used in combination with 10-40% of a non-functional dipodal silane, where the conventional coupling agent provides the appropriate functionality for the application, and the non-functional dipodal silane provides increased durability.

3、Limitless silanes

Silane coupling agents have the unique chemical and physical properties to not only enhance bond strength, but also prevent de-bonding at the interface due to use and aging, especially in humid conditions. The coupling agent provides a stable bond between two otherwise poorly bonding surfaces.

4、Vinyl Silanes as crosslinking agent, adhesion promoter and surface

SiSiB vinyl silanes, also called vinyl silane or ethenyl silane. SiSiB vinyl silanes are bifunctional organsilanes with a reactive vinyl group and hydrolysable inorganic trialkoxysilyl groups.

5、Silane Coupling Agents

What are Silane Coupling Agents? Silane coupling agents are compounds whose molecules contain functional groups that bond with both organic and inorganic materials. A silane coupling agent acts as a sort of intermediary which bonds organic materials to inorganic materials.

Silane Coupling Agent

Silane coupling agents are primarily used in reinforced plastics and electric cables composed of crosslinked polyethylene. Other uses include resins, concrete, sealant primers, paint, adhesives, printing inks and dyeing auxiliaries.

Silane Coupling Agent

There are three basic approaches for using silane coupling agents. The silane can be used to treat the surface of the inorganic materials before mixing with the organic resin or it can be added directly to the organic resin or holistic mixing (in organic-inorganic mixture).
